Zoneadm install fails without intermediate directories in path construction

I'm using the following image:

 $ tar -tvf /opt/oxide/cockroachdb.tar.gz

The contents of oxide.json are as follows:

{"v":"1","t":"layer"}

I configured the zone using a pretty normal zonecfg:

pfexec zonecfg -z testzone                                                            
testzone: No such zone configured                                                              
Use 'create' to begin configuring a new zone.  
zonecfg:testzone> create                                                                       
zonecfg:testzone> set brand=omicron1                                                           
zonecfg:testzone> set zonepath=/zones/testzone 
zonecfg:testzone> set autoboot=false           
zonecfg:testzone> set ip-type=exclusive 
zonecfg:testzone> exit 

But when attempting to install the package, I see the following error;

$ pfexec zoneadm -z testzone install /opt/oxide/cockroachdb.tar.gz                      
INFO: omicron: installing zone testzone @ "/zones/testzone"...

Error: No such file or directory (os error 2) 

As some baseline checks:

• /opt/oxide/cockroachdb.tar.gz definitely exists on my system
• /zones/testzone/root definitely exists, but none of the files from cockroachdb.tar.gz appear unpacked in that filesystem.

For whatever it's worth, pkg info omicron1 shows the following version:

Were I to hazard a guess, it's likely because your tar file doesn't include /opt or /opt/oxide directory entries and we're probably not creating missing parent directories automatically. I'll take a look at the code, but if you want a workaround for right now, make sure those entries appear in the archive.

Ah, perfect, that seems to be the fix. I'm manually injecting:

• root
• root/opt
• root/opt/oxide

And things appear to be working! (Well, the "install is complete, probably", and what more can I ask for)
